GRAIN-HEADER ATTACHMENT FOR TRACTOBS.

Specification of Letters latenti Patented Aug. 5, 1919.

Application flied February 15, 1919. Serial No. 277,282.

- partlcl nrly as an llI'lPl'UVQIHOlll) upon the detanheble grain headeror header attachment constituting the subject matter of my contemporaryapplication filed Dccember 1, 1917, Serial Number 21.14 936; and itconsists inthe. improved general construction, in the improved moons foradjusting and adjustahly fixing the header, and in the improved meansfor driving the working parts of the header from one of the groundwheelsof the tractor, as hereinafter described an definitely claimed.

In the accompanying drawings, hereby mode a part hereof:

Figure l is n broken view partly in clown tion and partly in section midshowing the trwrtor and header.

Fig. 2 a plan view of the some.

Fig. 3 a detail. section showing the pimt her, one of the upright armspivoted on said 80 bar, and one. of the rcnrwnrdly extending arms of theheader frame connected to said upright arm below the. pivot her.

Fig. 4- is a detail of the driving, connection to the working parts ofthe header.

Fig. 5 is a detail view of the rear portion of thofnmin adjusting lever.

Fig. 6 is a. detail showing the connection of the forward portion ofsaid mnin adjust ing lever.

Similar numerals designate corresponding-parts in all of the. views ofthe drawings.

The tractor 1 in general is of the ordinary well known (xmstrnction. andin furtherenc of my invention one of its ground 'wheels 2 and which ispreferably a. traction wheel, is equipped with a sprocket gear 3. 011said. 5 rocket gear 3 is mounted it sprocket be t 4 which is alsomoonicd on a sproel rear 5. Fig. 4, fixed on a. transverse shaft 6 that.is journalcd in a casing 7 car:

ried by n sn 'iplenicnt'al frame 1 to the tram.

tor frame. Said shaft fi-hns fixed thereon oppositely beveled gears 7and 8. The gear 7 is intermeshed with a beveled gear 9 on a. stub shaft10, while the beveled gear 8 is inter-meshed with a beveled gear 11 on astub shaft 12. The stub Shaft 10 is connected through a universal jointwith a shaft 13 for transmitting motion to the apron of the header, andthe stub shaft 12 is connected through a similar joint with a shaft 14for transmitting motion to the elevator of the header, as hereinafterdefinitely set forth.

Secured to the tractor frame at a. point intermediate of the frontwheels and the rear wheels is a transverse pivot bar 9 that extendslaterally beyond the wheels at both sides of the tractor. Pirated atintermediate mints of their length on the said bar 9 are upright arms 3which are connected together at their upper ends by a cross-bar 3. Fig.2. The head"? platform 12* is provided with. renrwardly. extending arms4", the rear ends of which are adjustably connected with the lower endsof the upright hrms 3. Pivoted on each arm 3* is a bearing sleeve 15 nwhich is supported for rotation an internally threaded tube 16, heldagainst en lwise movement in the bearingl5 and equipped with it handwheel 18,'whereby it may he. turned. about its axis: Threaded into thetubes 16 are rods l9, the lower ends of which are pivotally connectedwith the arms 4. :By turning the hand wheels 18 the arms 4" may bereadily raised or lowered lo properly position the header platform 12".

'1 he su iplemental frame 1" is extended laterally at opposite sides ofthe tractor, as shown in Fig. 2, and connected to and in terposedbetween the laterally extended frame portions and the upper )ortions ofthe upright arms 3 are retracti e springs 6". The connections betweenthe upper ends of said springs and the, arms 3* are effected by links5*. and manifestly the springs will operate to eonnterlmlnnco the weightof the header.

Arranged transversely above the forward,

- the arm 17 will he attended by upward movement of the header platform12/, while forward movement of the arm 17 will be attended by downwardmovement of said platform 12". Movable with or on the transverse rod 7",thou h independently of the arm 7* is the hen lever 8" for the manualraising and lOWBIlIlg of the header platform. Said lever 8 is providedat 11 with a detent to engage a curvilinear rack 10* fixed with respectto the tractor cab, and designed to rmit of the header platform beingadjust ly fixed. Extending loosely through a guide 30 on the. hand lever8* is a rod 12" connected at its forward end to the upperortion of thearm 17. At its rear end sai rod 12" is connected to a hand lover illthat is pivoted on the hand lever 8 and is provided with a detent 32 toengage a mental rack 33 on the hand lever B, it being remembered thatthe arm 17 is movable independently of the lever 8*, it will be readilyunderstood that without movement of the lever 8 the header platform 12may be raised or lowered to a'slight extent/-11 6., may be niceladjusted through-the medium of the hand ever 31. and without movement ofthe hand lever B. When, however, material movement of the headerplatform 12" is desired, such movement is effected through the medium ofthe hand lever 8", and then said hand lever B is adjustably fixed tomaintain the header platform 12 in the posit-ion desired.

The header platform is provided with cutting apparatus 36 and also anapron 27,

the latter being trained over rollers at the ends of the platform, oneof the rollers bo ing connected through a universal joint 39 with a.shaft section 40 of angular form in cross-section which is movableendwise but held against turning in a socket portion 41 of the shaft 13.

Supported for swinging movement on the header-platform is an elevatorframe 46 having opposed aprons the lower rollers of which are connectedby gearing, and one of which rollers is connected through a universaljoint 47 with an angular shaft 48 which is movable endwise in hut turnswith the socket portion of the shaft 14. Thus it will be manifest thatnotwithstanding motion is taken from theshafl fl. the rouvtgvcr apron 27and the opposed aprons of the elevator will be driven m the properdirections.

Supported in proper relation In one cutting apparatus and the u )I'Ull27 is a reel 50 on a shaft 31, which shaft is equipped with a beveledgear 52 iutcruu-sluul with a hovclcd gum- :l 'l on an cudwiso i-xtcnsihhshaft 54, the rear section of which is equipped with u sprockct gear5-3, connected through a sprocket hclt 513 with n sprocket gen: 57 onthe roller shaft that derives motion from the shaft 13.

A her (50 on the elevator frame carries a pulley lJlock (51, a similarpulley block (52 being carried on a supporting bar 63. Con ucclcd with abracket (ll extending at one side of the block (31 is one end of a cable65, the said cable being reeved through the pulley block and connectedwith a drum 66 that is mounted on the pivot bar 9. The said drum isequipped with a crank 68, and is provided with a ratchet (39 designed tobe engaged by a pawl 70 with a view to preventing retrograde rotat ion.Manifestly rotation of the drum 66 will he attended by raising orlowering of the free end of the elevator frame.

It will be apparent from the foregoing. that the im iu-ovei'ncnts hereindisclosed constitute steps forward in the art and increase the practicalutility of the tractor constituting the subject matter of my lfl-forecited header attachment for tractors.

Having described my invention, What I claim and desire to secure byLetters'Patout, is:

1. The combination of a wheeled frame, a transverse ivot bar mounted onthe frame and exten in laterally beyond the sides thereof, uprig t armspivoted onthe end portions of said bar and extendin above and below thesame, a header positioned in front of the frame and having rearwarcllyextending arms ivotally connected to the upright arms be ow the pivotbar, means connecting the upper portions of the upright arms and theforward portions of the rearwardly extending arms, an upwardly extendingarm mounted on the frame and connected with the upper portions of saidupright arms, a lever mounted on the frame and movable independently ofsaid u wardly extending arm, means whereb 831d lever may be ad ustablfixed to the rame, a hand lever mounte on the first-named lever, aconnection between said secondnamed lever and the upwardly extendi arm,and means whereby the second-nu lever maybe adjustably fixed withrespect to the firsbnamed lever.
